Letters Patent No. 87,341, dated March 2, .1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Beit known that I, BARTON H J ENKs, ofridesburg, in the county ofPhiladelphia,and State ofPe-unsylvania, have invented' certain new and useful Improvements in the Harness-Movements of Looms; and Ido hereby declare that the following'isy a full, clear, and exact description thereof', reference being had to' the accompanying drawings, making a part of this specification, in which Figure 1, plate 1, is a section through the loomframe, taken in the course indicated by red line y y in fig. 2.

, Figure 12, plate 1, is a section taken through the lioom, in the vertical plane indicated by red line x in Figure 3, plate 2, is a plan view ofthe loom.

Figure 4, plate 2, is a sectional view,`in detail, of

the upper portion of one of' the standards which support the heddles. l

Similar 'letters of' reference indicate corresponding parts in the several figures. y

One ofi the objects of my invention is to effect, directly, the drawing down or depression of heddleframes,by means of oscillating drums, to which saidv frames are connected by means of straps, in such manner that when' one or. more heddles are raised, the other heddle or heddles, which are in connection therewit-h, will be depressed or moved in a direction opposite to the motion of the'grising heddle or heddles, as ,will be hereinafter explained. V Another object of my invention is to arrange a part of the whole number of' treadles used in the loom for moving the heddle-frames, ou each side of' the loomf'rame, when the treadles thus arranged are connected to'and operate directly upon the top rollers, from which the heddle-fiames are suspended, said treadles being actuated by Vseparately-movable cams upon the camshaft, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings- A represents the frame of the loom, which may be -constructed in any suitable, well-known manner; and

B B representstandards, which are erected on both sides of the loom-frame, for sustaining the heddleframes C G O, three of which frames 'are represented in the drawings.

The upper ends of the two standardsB B are enlarged in a suitable manner, so as to form bearingheads, c a, whichare adapted for receiving the jonrnals of rollers, D D D, and sustaining these rollers, one above another, in different vertical and horizontal planes, as clearly shown in figs. 2 and 4.

Each one of these Arollers D has -f'our flanged drums, b b, c c, keyed upon it, as shown in tig. 1.

The drums b b have straps, b b', attached to them,

by means of which a heddle-frame, 0,-is suspended by both ends.

The drumsc o are connected, by means of straps, c

c', and rods or wires, cl d, to the free ends of the treadles EE, which latter are applied beneath, and at,

right angles to a transverse crank-shaft, F, as shown.

The straps c c', of all the drums c c, are passed around these drurrs, in opposite directions to the susby means of' straps e e, to 'horizontal drums G, in vsuch manner that these heddle-frames are held down in place, under proper tension, and caused to descend at proper times.

The straps e are attached, on opposite s ides of they drums G, in such manner that while" oieV or one `set of heddles is elevated, they willlcause said drum or drums to rotate in a direction which will cause a de pression of the opposite heddle, or set of heddles, as the case may be. i

This is effected, as shown in figs. l and 2, by applying the straps e to the drums G, so that, when one strap or set of' straps is being unwound from them, the opposite strap, or set of straps, will be correspondingly wound from them.

The drums G have their end-bearings in arms HH, which are secured between transverse bars, A A', of the frame A, in a suitably-inclined position, to keep the heddle-frames from contact with each other "at p l their lower ends.

It will be seen, from the above description, that the upper horizontal rollersD D D are arranged upon an inclined plane, in such manner that the heddle-f'rames hang free from each other; consequently these frames, y i

and their appurtenances, will not be chafed or worn out by rubbing against each other; and, while this is the case, the arrangement of the said rollers D D will admit of the heddle-fi'ames being hung very closely together.

It will also be seen, from the above description, that one set of the heddle-ames is drawn downv by the operation ofthe treadles in raising another set.

I am aware that it isnot new to hold heddle-frames between two sets of rollers, or sheaves, one.` set. being arranged below these frames, and the other set being arranged above them, with flexible cords or strap-connectionspassing around said rollers, or sheaves, and

attached to vibrating arms applied on the sides of' the.

loom-frame.

My arrangement differs from that `just referred to, in that the lower-.rollers or drums G are so connected to the heddle-frames, that the descent of' these frames is `effected through the medium of' the upper rollers D,

treadles, the drums being oscillated the heddle-frames upon them, as

acted upon by the by the operation of described.

I also am aware that an auxiliary pulley and strap vhave been used, in connection with upper and lower drums and straps, for the purpose of working heddleframes; but I am not aware that an arrangement, whereby the\lesired movements of the heddle-frames have been et lcted directly by the rollers and heddlesuspending straps, i'n the manner shown; that is to say, only' the ioller or pulley-straps being attachedl to the treadle-frames, the actuating-straps and rods being attached to treadles outside of the range of the heddie-frames. V

The treadles E E E are arranged partly upon one side of the loom, and partly upon the opposite side thereof, as shown in the drawings, and these treadles are connected directly to the ends of the upper rollers D, from `which the heddles lO are suspended, so that the power required to move the heddles equally distributed upon both ends of said rollers.

I am aware that a loom has been constructed before my invention, having two sliding cams in the middle of' the loom-frame, actuating treadles which were dii rectly attached to the bottom bars of the heddle-frames or harness.

I am also aware that, in very wide looms, two sets of treadles and cams have been placed at considerable distance apart, so could be depressed or., raised evenly; but, in such cases, the treadles acted directly upon the heddles.

I am also aware that looms have been heretofore constructed, having sliding cams on the outside ofthe loom-frame, which were attached to the harness by cords and levers, as in Letters Patent D o. 66,827.

And, finally, I am aware that looms h'ave been made, havngtheir treadles attached to top rollers, from which the heddles were suspended; but such treadles, and their cams, were arranged in the centresof theselooms, and their connecting-wires passed between the heddles, and. through the warp, which is a serious objec tion, remedied by my improvement.

that theoheddle-frames or harness Each set of treadles E, in my improved loom, is ar ranged between the ends of the heddles and the side of the loom-frame, so that the connecting-wires 'do not pass through the warp, nor between the heddles, notwithstanding these Wires are attached to the top suspension-rollers of the heddles.

This arrangement requires the use of two sliding cams, P P, one for each set of treadles, which cams are applied to grooved hubs, S, and operated so as to receive laterally-sliding movements upon their shaft, F, substantially. as described in the Letter's Patent numbered 4,645.

The drawings represent the cams, and their hubs, applied upon rectangular portio'ns of the cam-shaft F; but I do not lay claim to this feature as my invention, it having been invented prior to its use by me.

Having described my invention, f

What I claim as new, and desire to secure by Letters Patent,`is-

p 1. The combination, with treadles arranged at each side of' the loom, of straps and rollers, the straps being connected directly to the rollers from which the heddle-frames are suspended, and by which they are actuated, substantially. as described.

2'. The combination of laterally-sliding cams P, treadles E E, which are placed at both sides of the loom,'and the suspension-rollers D, and straps connected directly to the rollers, substantially as described.

3. Drawing-down drums G, arranged beneath the hedd1es, and having the latter attached to them, substantially as described, in combination with treadles E E, and straps c' c', arranged outside of the range of the heddle-frames, substantially as and for the purpose described.

4. Straps d, rollers D, heddles C, straps e, and drawthe purpose described.
